COMBINED DOOR CLOSER AND CHECK.

Specification of Letters Patent. i

Patented May 25, 1915.

I Application lcd April 7, 1914( Serial No. 830,191.

To all whom it may concern:

Be it known that I, HENRY G.' VOIGHT, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Im rovements in\`Combined Door Closers` and hecks; and I- ydo hereby declare the following to be a full, clear, and

' exact description of the invention, such as will enable others skilled in the art to which it a pertains to make and use the same.

y invention-relates to animprovement in combined door closer and check. M

The ordinary door closer and check comprises a cylinder, a piston in the cylinder, a spring. for actuating the piston in a direction to close the door and a liquid acting against the piston for checking the closing movement of the door. When the door is. closed "the liquid re'sts in advance of the piston and movement of the as the door is opened by hand, the liquid is thrown or forced by the piston against the gland or stuffing box and more or less lof it seeps, or is forced-through the stuffing box and escapes, due to the pressure of 'the piston against the same.

The object ofthis invention is to provide means for protecting the stuiling box from the pressure of the liquid during the opening iston, and 1t consists in a delector projectmgfrom the head of the cylinder `and in a position to deflect the liquid from the stu box, and prevent it from being lcompresse against the head of the cylinder adjacent the stuiling box.

In the accompanying drawings, Figure 1 is a view in sectlon cfa combined door closing and checking cylinder 4showing my improvement therein and Fig. 2 is a view of the delector detached.

1 represents a cylinder, and 2 the head thereof provided with an inwardl projecting boss 3, concentric with the stu g -box 4.

vThe boss 1s provided with a central opening for the piston rod 5 to which the piston 6 is secured, and the piston is provided' with any of the well known means for permitting the liquid to ow freely to the rear thereof during the opening movement of the door, and for checking the piston during the closing movement, and is engaged by a spring 7, which when the door is released, forces the piston rearwardly and operates through the door actuating mechanism to close/the door, the checking liquid operating to control or check the closing action of the spring.

When the door is thrown open, at times cylindrical with a rounded lower end as shown. I have shown it provided with internal threads which engage external threads` on. the boss 3, but I may secure it. by friction or by set screws. The piston passes centrally through the delector. and the latter. is provided with one or more ho-les 9 which permit'the liquid to flow into and out of the deflector, but Whichare not large, or numerous enough to permit of sufficient liquid to pass into the deflector during an opening movement, to create any pressure therein consequently there is no chance for lpakage of the liquid through the stuliing I have shown the means disclosed in Patent No. 1,085,070 granted to me January 20th, 1914, for permitting the liquid to pass from one side of the piston to the other, but

' I do not confine myself to such details,

It is evident that changes may be made in the shape of the deflector and the manner of securing it to the head of the cylinder hence I would have it understood that'I do not confine' myself to. these details but consider myself atlliberty to make such changes as may fairly fallwithin the spirit of my invention.

, Having fully described my invention what y I I claim as new and desire to secure by Letters-Patent, is y1. In a liquid door check and closer, a cylinder, a, piston therein, a spring for movingv the piston in a direction to close the door, and a rigid unyielding defiector secured to the head and forming a. chamber around the piston rod opening through 'the head the said chamber having restricted communicalos 4ing furthe liquid, the said ideieetor forming piston rod, and with a restricted opening for a. partly closed chamber around the'lpiston ythe liquid, the said deiector forming a rod-opening through the head. partly yclosed chamberaround the piston rod 3.
